.SH Synopsis
   Defined in header <ios>
   typedef /*implementation-defined*/ streamsize;

   The type std::streamsize is an implementation-defined signed integral type used to
   represent the number of characters transferred in an I/O operation or the size of an
   I/O buffer. It is used as a signed counterpart of std::size_t, similar to the POSIX
   type ssize_t.

   Except in the constructors of std::strstreambuf, negative values of std::streamsize
   are never used.
